AFL boss Andrew Demetriou says Essendon coach James Hird is entitled to due process as investigations into allegations of drug use and the club's supplement program continue.

Hird was interviewed by the Australian Sports Anti-Doping Authority (ASADA) on Tuesday, but has refused to reveal publicly what he told investigators.

Demetriou says Hird's response is appropriate and the investigation must be allowed to run its course.

"He's absolutely doing the most appropriate thing," Demetriou said.

"He's responding to the investigation in accordance with the proper process of the investigation, with the ASADA investigators, with his legal representatives. He's entitled to go through that process."

Demetriou denied putting pressure on Hird to step down while the investigation is completed.

He says his comments last week were misunderstood.

"I didn't actually call for him to stand down at all," Demetriou explained.

"What I said was that James Hird, going through his thought process, I'm sure that's one of the things he's considering."

Demetriou said he was happy with how the code has reacted to the Australian Crime Commission report on doping in sport.

The report, released in February, sparked a series of investigations across several codes into allegations of drug use by athletes.

Demetriou says the AFL has been very clear of what its position is on drugs in sport.

"We have met individually with the presidents, coaches and chief executives of all clubs to brief them and reinforce the standards that we expect them to uphold to protect the integrity of our game," he said.

"We have now almost completed a second round of meetings with the clubs, their playing groups, their staff and coaches because we want everyone to know that a win-at-all-costs mentality is not acceptable."
